    摘要: A system for determining an axle load for an agricultural tractor. The system includes an axle or wheel suspension device arranged on a front axle of the agricultural tractor and has a hydraulic spring strut having a hydraulic cylinder and a hydraulic piston dividing the hydraulic cylinder into an annular space and a piston space. A first pressure sensor detects a first working pressure, which is present in the annular space. A second pressure sensor detects a second working pressure, which is present in the piston space. A control device calculates a front axle load variable which represents an axle load acting on a front axle on the basis of a pressure force difference derived from the first and second working pressures.

    摘要: In a suspension controlling apparatus for a vehicle which includes a suspension whose damping force is variably settable and a control unit capable of executing skyhook control on the basis of target damping force for skyhook control to control the damping force of the suspension, the vehicle stability is raised upon skyhook control during turning of the vehicle. Target damping force limit value determination device provided in a control unit determines target damping force limit values for skyhook control such that a value obtained by subtracting, from the target damping force limit value on the decompression side when the suspension is in a decompressed state, the target damping force limit value on the compression side when the suspension is in a compressed state increases as a roll angle detected by a roll angle sensor increases. The control unit limits the target damping forces with the target damping force limit value.

    摘要: A shock absorber includes: at least one cylinder apparatus including a cylinder sealingly containing operating fluid, a piston slidably fittedly inserted in the cylinder to divide an interior of the cylinder into two chambers, and a piston rod coupled to the piston and extending to an outside of the cylinder; and at least one damping force generation mechanism connected to the cylinder apparatus, and capable of generating a damping force to be applied to a flow of the operating fluid caused by a movement of the piston and adjusting the damping force from the outside. The damping force generation mechanism includes a damping valve for generating the damping force, a pilot chamber for applying a pilot pressure by the operating fluid to the damping valve, and a pump for at least supplying or discharging the operating fluid to or from the pilot chamber.
